TLSR8258F512ET32

TLSR8258F512ET32 is a Telink BLE 5.1 wireless SoC with BLE Mesh and multi-antenna AoA/AoD support, 512 KB flash, 64 KB SRAM, in QFN-32 — the low-cost mesh-networking chip for smart lighting, ESL tags, beacons and HID devices. The integrated BLE Mesh stack on a 32-bit proprietary RISC core (up to 48 MHz) is the selection point: lighting and sensor nodes run a full mesh without an external network processor, with hardware AES/AES-CCM and ECC acceleration for secure provisioning. Selection advice: this is BLE 5.1, not 5.4 — verify the Bluetooth version claim against the Telink datasheet when comparing with newer 5.4 SoCs. The F512 denotes 512 KB flash (the F1K variant doubles it for larger stacks); the T32 suffix is tape-and-reel QFN-32 packing. Supply is 1.8 to 3.6 V, -40 to +85 °C, with 10 dBm TX and -93 dBm RX sensitivity, so coin-cell designs are realistic — but budget RF matching and antenna design per the Telink reference layout. Parameters verified against the Telink TLSR8258 datasheet (DS-TLSR8258-E18) and Mouser listings.
